Keo 919-000-951 Countersink 3/16 in 90 Degree Carbide

Product Description

The KEO 919-000-951 is a single-flute solid carbide countersink designed for precision chamfering, countersinking, and deburring operations in metal fabrication and machining applications. With a 3/16-inch head diameter, a 90-degree included angle, and a 3/16-inch shank diameter, this tool is built for consistent, controlled material removal on small-diameter holes. The solid carbide construction provides hardness and wear resistance suited to demanding cutting conditions. The overall length is 2.0 inches. At 0.01 pounds, it is a compact, lightweight tooling solution for bench-top or machine-mounted use.

This countersink is applied in chamfering and deburring operations across general machining, sheet metal work, and precision part finishing. The 90-degree included angle is a standard geometry for fastener seat preparation, making this tool appropriate for creating clean screw or bolt entry points in metal, composite, or hard plastic workpieces. It is sized for use in smaller-scale applications where a 3/16-inch maximum cutting diameter is sufficient for the required hole geometry.

Key Features

• Solid carbide construction for superior hardness and extended tool life
• 90-degree included angle - standard geometry for fastener chamfering and countersinking
• Single-flute design for controlled, precise material removal
• 3/16-inch head diameter and 3/16-inch shank diameter for compact fitment
• Suitable for chamfering, countersinking, and deburring in a single tool
• Lightweight at 0.01 pounds with a 2.0-inch overall length

Compatibility

Designed for use in standard machining setups requiring a 3/16-inch shank mount; suitable for chamfering and countersinking applications where a 90-degree included angle and up to 3/16-inch maximum cutting diameter are specified.

Installation Notes

This tool is installed by machinists and tooling technicians in drill presses, CNC machining centers, or hand-held rotary equipment with a compatible 3/16-inch shank collet or chuck. Always bring the spindle to a full stop before changing tooling. Verify workpiece is securely clamped before beginning the cut. Follow shop-specific feeds and speeds guidelines for carbide tooling on the target material.
